He ran tough, put up some nice gains... even though Houston KNEW he was going to get the ball. Not bad for a 35 year old running back.
Imagine what he could have done at 28... which is about the age that any FA that we bring in will be.
Those that say, never bring in a FA RB, they always suck... are wrong.
If they'd say, "never bring in a high-priced free-agent," then I'd agree with them. That isn't smart. But bringing in a guy to get 10-12 carries, for a reasonable sum... that is a perfectly sensible decision.
